Buy the Sigma 150 Macro.
Do I mean 180mm?
Yes, I do.
The Sigma 180mm f/3.5 EX DG APO Macro IF lens is a high performance
telemacro lens that can focus from infinity to full 1:1 lifesize
reproduction without accessories.
Convenient for photographing subjects which are not easily approached,
the 180mm f/3.5 Macro features apochromatic design, two SLD (Special
Low Dispersion) glass elements, and a floating inner focus (FIF)
system. A focus limiter switch aids in faster AF by restricting the
movement of the focusing mechanism to a smaller portion of its
enormous range. Usable with Sigma's 1.4X EX teleconverter as a 252mm f/
4.9 lens or with the 2X EX teleconverter as a 360mm f/7 lens in manual
focus only.
This lens is designed as a high-quality macro lens, good for film or
digital SLR cameras. The improved DG lens design corrects for various
aberrations. This macro lens is specially coated to get the best color
balance whilst cutting down on ghosting caused by reflections from the
digital image sensor. The lens provides the utmost correction against
lateral chromatic aberration which is a serious problem for digital
SLR cameras.
• Close focus capability of 18"
Sigma # 105109 - $725 at B&H ($26 a month if you're
strapped) :-)
